我有从 Oracle atom 提要返回的 xml,我将它临时存储在名为“ATOM”的 apex_collection 中。
XML 如下所示:

到目前为止,我的 SQL 查询是这样的,并且工作正常:
with t as (select clob001 from apex_collections where collection_name = 'ATOM')
SELECT title, summary, content FROM t,
XMLTable( XMLNamespaces(
'http://www.w3.org/2005/Atom' AS "ns0"
), 'ns0:feed/ns0:entry'
PASSING XMLTYPE.createXML(t.CLOB001)
COLUMNS title VARCHAR2(4000) path 'ns0:title' ,
summary VARCHAR2(240) path 'ns0:summary',
content VARCHAR2(4000) path 'ns0:content');
但我需要获取内容标签内的信息,它看起来好像是它的 JSON。我知道如何用 SQL 解析 JSON,但如果 JSON 在 XML 文档中,我不知道如何解析它。
